  • C# WinForms: How to load an image, then wait a few seconds, then play a mp3 sound ?

    - by ibmkahm
    Hello everybody, (after pressing a button) i would like to show an image (using a picturebox), wait a few seconds and then play a mp3 sound, but i dont get it to work. To wait a few seconds i use "System.Threading.Thread.Sleep(5000)". The problem is, the image alway appears AFTER the wait time, but i want it to show first, then wait, then play the mp3... i tried to use "WaitOnLoad = true" but it doesnt work, shouldn't it load the image first and the continue to read the next code line ?? Here is the code i've tried, that doesnt work: private void button1_Click(object sender, EventArgs e) { pictureBox1.WaitOnLoad = true; pictureBox1.Load("image.jpg"); System.Threading.Thread.Sleep(5000); MessageBox.Show("test"); //just to test, here should be the code to play the mp3 } (i also tried loading the image with "LoadAsync" and put the code to wait and play the mp3 in the "LoadCompleted" event, but that doesnt work either...) would be very nice if somebody helps me

  • segmented reduction with scattered segments

    - by Christian Rau
    I got to solve a pretty standard problem on the GPU, but I'm quite new to practical GPGPU, so I'm looking for ideas to approach this problem. I have many points in 3-space which are assigned to a very small number of groups (each point belongs to one group), specifically 15 in this case (doesn't ever change). Now I want to compute the mean and covariance matrix of all the groups. So on the CPU it's roughly the same as: for each point p { mean[p.group] += p.pos; covariance[p.group] += p.pos * p.pos; ++count[p.group]; } for each group g { mean[g] /= count[g]; covariance[g] = covariance[g]/count[g] - mean[g]*mean[g]; } Since the number of groups is extremely small, the last step can be done on the CPU (I need those values on the CPU, anyway). The first step is actually just a segmented reduction, but with the segments scattered around. So the first idea I came up with, was to first sort the points by their groups. I thought about a simple bucket sort using atomic_inc to compute bucket sizes and per-point relocation indices (got a better idea for sorting?, atomics may not be the best idea). After that they're sorted by groups and I could possibly come up with an adaption of the segmented scan algorithms presented here. But in this special case, I got a very large amount of data per point (9-10 floats, maybe even doubles if the need arises), so the standard algorithms using a shared memory element per thread and a thread per point might make problems regarding per-multiprocessor resources as shared memory or registers (Ok, much more on compute capability 1.x than 2.x, but still). Due to the very small and constant number of groups I thought there might be better approaches. Maybe there are already existing ideas suited for these specific properties of such a standard problem. Or maybe my general approach isn't that bad and you got ideas for improving the individual steps, like a good sorting algorithm suited for a very small number of keys or some segmented reduction algorithm minimizing shared memory/register usage. I'm looking for general approaches and don't want to use external libraries. FWIW I'm using OpenCL, but it shouldn't really matter as the general concepts of GPU computing don't really differ over the major frameworks.

  • Retain Count Question: Some Guidance, Please

    - by yar
    [I'm sure this is not odd at all, but I need just a bit of help] I have two retain properties @property (nonatomic, retain) NSArray *listContent; @property (nonatomic, retain) NSArray *filteredListContent; and in the viewDidLoad method I set the second equal to the first (so now the retainCount is two, I think): self.filteredListContent = self.listContent; and then on every search I do this self.filteredListContent = [listContent filteredArrayUsingPredicate:predicate]; I thought I should do a release right above this assignment -- since the property should cause an extra retain, right? -- but that causes the program to explode the second time I run the search method. The retain counts (without the extra release) are 2 the first time I come into the search method, and 1 each subsequent time (which is what I expected, unfortunately). Some guidance would help, thanks! Is it correct to not release?

  • How to return focus from GridView or DataGrid to other control on the page

    - by Senthilkumar
    I Want to know how to focus to control after completing tab navigation for the grid view. I have certain controls in my page and GridView/DataGrid as last control, when I navigate (Tab key navigation) on my page. I can navigate from first control to GridView but when I finish all editable items in grid the tab control goes to browser address bar. I need this should focus to again first control on the page. My question is how can I do this? If it is an ordinary controls then I can use (on key down) attribute of the same.. here how can I get access to the last row's last column on the grid view.

  • How to update NSMutableDictionary. My code doesn't work.

    - by dawatson833
    I've populated an array using. arrSettings = [[NSMutableArray alloc] initWithContentsOfFile:[self settingsPath]]; The file is a plist with the root as an array and then a dictionary with three three keys defined as number. I've also tried setting the keys to string. I display the values in the plist file on a view using. diaper = [[arrSettings objectAtIndex:0] objectForKey:@"Diaper Expenses"]; oil = [[arrSettings objectAtIndex:0] objectForKey:@"Oil Used"]; tree = [[arrSettings objectAtIndex:0] objectForKey:@"Wood Used"]; This code works fine, the values in the dictionary are assigned to the variables and they are displayed. The user can make changes and then press a save button. I use this code to extract the dictionary part of the array so I can update it. The assignment to editDictionary works. I've double checked the key names including case and that is correct. editDictionary = [[NSMutableDictionary alloc] init]; editDictionary = [arrSettings objectAtIndex:0]; NSNumber *myNumber = [NSNumber numberWithFloat:diaperAmount]; [editDictionary setValue:myNumber forKey:@"Diaper Expenses"]; myNumber = [NSNumber numberWithFloat:oilAmount]; [editDictionary setValue:myNumber forKey:@"Oil Used"]; myNumber = [NSNumber numberWithFloat:treeAmount]; [editDictionary setValue:myNumber forKey:@"Wood Used"]; In this example I've used a nsnumber. But I've also tried the xxxAmount field as part of SetValue instead of creating a NSNumber. Neither implementation works. Several strange things happen. Sometimes the first two setvalue statements work, but the last setvalue fails with a EXC_BAD_ACCESS failure. Other times the first setValue fails with the same error. I have no idea why the first two sometimes work. I'm at a loss of what to do next. I've tried several implentations and none of them work. Also, in the debugger how can I display the editDictionary elements. I can see editDictionary, but I don't know how to display the individual elements.

  • iphone simulator crashes when it tries to access user location

    - by kevin Mendoza
    for some reason my code causes my program to crash. does anyone know why or how to fix it? NSLog(@"here"); CLLocation *location = [locationManager location]; [mapView removeAnnotations:mapView.annotations]; NSUserDefaults *defaults = [NSUserDefaults standardUserDefaults]; CLLocationCoordinate2D workingCoordinate = [location coordinate]; NSLog(@" this is %@", workingCoordinate.latitude); it makes it to the first NSLog, but somewhere between the first and second it crashes. My guess is that it has to do with the CLLocation *location line.

  • Active record taking Date.today as yesterday

    - by Mongus Pong
    I have a strange one.. I am doing something like : tip = find (:first, :conditions => ["last_shown = ? or last_shown is null", Date.today]) And then a little later on I do : tip.last_shown = Date.today tip.save When I look at output of these queries, ActiveRecord is doing the first query with todays date as I would expect. However, the send query, ActiveRecord is setting the last_shown date to be yesterdays date. Why on earth would it do this? I have config.time_zone = 'UTC' in my environment.rb. I can use Time.now.utc.to_date instead of Date.today but it makes no difference.

  • Android pluginable application

    - by Alxandr
    I've been trying to create an android-application the last couple of weeks, and mostly everything has worked out great, but there is one thing that I was wondering about, and that is pluginability trough the use of intents. What I'm trying to create is basically a comic-reader. As of the version I use now, I open the application and get a list of commics that are my favourites, then I enter one to get a detailed view, and finally I enter a page. This is managed trough 3 activities. List, Details and Page. However, as of now the application can only read comics of one source (a specialiced xml-feed comming from my server), and I was hoping to be able to expand this a litle (also, the page-activity and some other stuff needs to be cleaned up in, so I'm thinking about remaking from scratch, and just take the first go as a learning-round). And I came up with an idea which I think sounds great, but I don't know if it's possible, but this is what I'm thinking about: The user enters the application and get an (first time empty) list of comics. The user hits a button to find comics, this launces an intent that says something like "find comic" or something like that. This should cause the system to display all matching activities. This would make it possible to provide different comic-providers trough different applications. Another activity kicks in and might displays some options to the user (for instance a file-browser), or might not (in the example of an xml-feed, which should just load). The list is returned to the first activity and displayed to the user. The second (find) activity is closed. The user picks a comic from the list. This should open some details-activity. The details-activity should receive a key which corresponds to the comic selected. This should be unique amongst the comic-providers. The details-view should get it's data trough some cind of content-provider, or an activity (whichever is most suited, if one of them is). The user can select a page. This should be the same routine as step 5. My question is, is this possible in the android system, and if it is, is it a bad idea? And also, is there any better way to achieve more or less the same thing?

  • Data table columns become out of order after changing data source.

    - by Scott Chamberlain
    This is kind of a oddball problem so I will try to describe the best that I can. I have a DataGridView that shows a list of contracts and various pieces of information about them. There are three view modes: Contract Approval, Pre-Production, and Production. Each mode has it's own set of columns that need to be displayed. What I have been doing is I have three radio buttons one for each contract style. all of them fire their check changed on this function private void rbContracts_CheckedChanged(object sender, EventArgs e) { dgvContracts.Columns.Clear();

} The issue is when I check a button the first time, everything shows up ok. I choose another view, everything is ok. But when I click on the first view the columns are out of order (it is like they are in reverse order but it is not exactly the same). this happens only to the first page you click on, the other two are fine. You can click off and click back on as many times as you want after those initial steps, The first list you selected at the start will be out of order the other two will be correct. Any ideas on what could be causing this?

  • Summarising (permanently) data in a SQL table

    - by Cylindric
    Geetings, Stackers. I have a huge number of data-points in a SQL table, and I want to summarise them in a way reminiscent of RRD. Assuming a table such as ID | ENTITY_ID | SCORE_DATE | SCORE | SOME_OTHER_DATA ----+-----------+------------+-------+----------------- 1 | A00000001 | 01/01/2010 | 100 | some data 2 | A00000002 | 01/01/2010 | 105 | more data 3 | A00000003 | 01/01/2010 | 104 | various text ... | ......... | .......... | ..... | ... ... | A00009999 | 01/01/2010 | 101 | ... | A00000001 | 02/01/2010 | 104 | ... | A00000002 | 02/01/2010 | 119 | ... | A00000003 | 02/01/2010 | 119 | ... | ......... | .......... | ..... | ... | A00009999 | 02/01/2010 | 101 | arbitrary data ... | ......... | .......... | ..... | ... ... | A00000001 | 01/02/2010 | 104 | ... | A00000002 | 01/02/2010 | 119 | ... | A00000003 | 01/01/2010 | 119 | I want to end up with one record per entity, per month: ID | ENTITY_ID | SCORE_DATE | SCORE | ----+-----------+------------+-------+ ... | A00000001 | 01/01/2010 | 100 | ... | A00000002 | 01/01/2010 | 105 | ... | A00000003 | 01/01/2010 | 104 | ... | A00000001 | 01/02/2010 | 100 | ... | A00000002 | 01/02/2010 | 105 | ... | A00000003 | 01/02/2010 | 104 | (I Don't care about the SOME_OTHER_DATA - I'll pick something - either the first or last record probably.) What's an easy way of doing this on a regular basis, so that anything in the last calendar month is summarised in this way? At the moment my plan is kind of: For each EntityID For each month Find average score for all records in given month Update first record with results of previous step Delete all records that aren't the first I can't think of a neat way of doing it though, that doesn't involve lots of updates and iteration. This can either be done in a SQL Stored Procedure, or it can be incorporated into the .Net app that's generating this data, so the solution doesn't really need to be "one big SQL script", but can be :) (SQL-2005)

  • match elements from two files, how to write the intended format to a new file

    I am trying to update my text file by matching the first column to another updated file's first column, after match it, it will update the old file.

  • jCarousel not working properly within tabbed menu

    Hi everybody, I'm riding three different jCarousel ul, one in each target of a tabbed menu designeb by Yetii. The problem issue is that the one in the first target works well, whereas the remaining two show just a slice of the first picture and slide soon onto a back frame. The jCarousel is initialized by a class as the behaviour required is the same for all targets: jQuery(document).ready(function() { jQuery('.jcarousel-skin-tango').jcarousel({ wrap: 'circular', //size:8, scroll:1, animation:.10, auto:5, }); }); The ul have different id. Tried also initializing the script by separate id but nothing changed. Any suggestion on it? Thanks in advance - Mauirizio

  • How can I use the FOR attribute of a LABEL tag without the ID attribute on the INPUT tag

    - by Shawn
    Is there a solution to the problem illustrated in the code below? Start by opening the code in a browser to get straight to the point and not have to look through all that code before knowing what you're looking for. <html> <head> <title>Input ID creates problems</title> <style type="text/css"> #prologue, #summary { margin: 5em; } </style> </head> <body> <h1>Input ID creates a bug</h1> <p id="prologue"> In this example, I make a list of checkboxes representing things which could appear in a book. If you want some in your book, you check them: </p> <form> <ul> <li> <input type="checkbox" id="prologue" /> <label for="prologue">prologue</label> </li> <li> <input type="checkbox" id="chapter" /> <label for="chapter">chapter</label> </li> <li> <input type="checkbox" id="summary" /> <label for="summary">summary</label> </li> <li> <input type="checkbox" id="etc" /> <label for="etc">etc</label> <label> </li> </ul> </form> <p id="summary"> For each checkbox, I want to assign an ID so that clicking a label checks the corresponding checkbox. The problems occur when other elements in the page already use those IDs. In this case, a CSS declaration was made to add margins to the two paragraphs which IDs are "prologue" and "summary", but because of the IDs given to the checkboxes, the checkboxes named "prologue" and "summary" are also affected by this declaration. The following links simply call a javascript function which writes out the element whose id is <a href="javascript:alert(document.getElementById('prologue'));">prologue</a> and <a href="javascript:alert(document.getElementById('summary'));">summary</a>, respectively. In the first case (prologue), the script writes out [object HTMLParagraphElement], because the first element found with id "prologue" is a paragraph. But in the second case (summary), the script writes out [object HTMLInputElement] because the first element found with id "summary" is an input. In the case of another script, the consequences of this mix up could have been much more dramatic. Now try clicking on the label prologue in the list above. It does not check the checkbox as clicking on any other label. This is because it finds the paragraph whose ID is also "prologue" and tries to check that instead. By the way, if there were another checkbox whose id was "prologue", then clicking on the label would check the one which appears first in the code. </p> <p> An easy fix for this would be to chose other IDs for the checkboxes, but this doesn't apply if these IDs are given dynamically, by a php script for example. Another easy fix for this would be to write labels like this: <pre> &lt;label&gt;&lt;input type="checkbox" /&gt;prologue&lt;/label&gt; </pre> and not need to give an ID to the checkboxes. But this only works if the label and checkbox are next to each other. </p> <p> Well, that's the problem. I guess the ideal solution would be to link a label to a checkboxe using another mechanism (not using ID). I think the perfect way to do this would be to match a label to the input element whose NAME (not ID) is the same as the label's FOR attribute. What do you think? </p> </body> </html>

  • C# Enum Flags Comparison

    - by destructo_gold
    Given the following flags, [Flags] public enum Operations { add = 1, subtract = 2, multiply = 4, divide = 8, eval = 16, } How could I implement an IF condition to perform each operation? In my attempt, the first condition is true for add, eval, which is correct. However the first condition is also true for subtract, eval, which is incorrect. public double Evaluate(double input) { if ((operation & (Operations.add & Operations.eval)) == (Operations.add & Operations.eval)) currentResult += input; else if ((operation & (Operations.subtract & Operations.eval)) == (Operations.subtract & Operations.eval)) currentResult -= input; else currentResult = input; operation = null; return currentResult; } I cannot see what the problem is.

On other pages I just want the good old fashioned form. Do I still need to change the weight? I know I am missing something elementary.

  • jQuery: Check whether val() has a specific value or not upon form submit

    - by Staffan Estberg
    Hi, I'm trying to check whether val() has a specific value or not inside a form, if so deleting the contents / preventing the form being submitted depending on if both fields are filled in (stringOne and stringTwo). There's a default text for each input field, the first being "Namn, telefonnr, sökord" and the second "Område, plats, ort". If a user only fills in the first field the second must be cleared before the form string is passed on and vice versa. Like so - // "This" refers to the form's submit button if (($(this).siblings('input.stringOne').val("Namn, telefonnr, sökord")) && ($(this).siblings('input.stringTwo').val("Område, plats, ort"))) { return false; // If nothing's filled in, then do not submit } else { // If either field is not filled in, clear it if ($(this).siblings('input.stringOne').val("Namn, telefonnr, sökord")) { $(this).siblings('input.stringOne').val() == ''; } if ($(this).siblings('input.stringTwo').val("Område, plats, ort")) { $(this).siblings('input.stringTwo').val() == ''; } } jQuery version 1.2.6.

  • Web Search API which allows automated queries

    - by Spi1988
    I need to develop a java desktop application which sends queries to a search engine in order to obtain the very first highest ranked pages (Example: the first 4 pages only). Some heavy processing needs to be performed on the retrieved pages, so the time between a query and another won't be less then a minute. I would like to know whether there is any web search API for java, suitable for my situation, i.e. which allows the use of automated queries? (since in my case, the queries are generated programatically, and not through user interaction) I have checked Google's AJAX Search API and also Yahoo's Search Boss, however they only allow queries triggered by direct user interaction.

    I am building a framework that will validate forms both client-side (javascript) and server-side based on a form requirements specification written in json. The purpose is to get rid of logically equivalent code on the server and client to make the code more maintainable, faster to write, and less buggy. The specification format may look something like: { '&lt;field_name>' : ['&lt;validation_function>', 'req', ['&lt;requirement>', &lt;param>], ...], ... } ( the requirement list is ordered so that the user can get most basic error messages first, the 'req' requirement must come first if it exists and means that the field is required) e.g.) { 'name' : ['string', 'req', ['min',6], ['max',150], ['match', /^[\sa-z0-9ÅÄÖåäö&]$/i], ['not_match', /^tmp_/]], 'email' : ['email', 'req'], 'email_confirm' : ['same_as', 'email'], 'password' : ['string', 'req', ['min', 6], ['max', 64], ['match', /^[a-z0-9\!@#\$%^&*_+.]$/i] ], } Does anyone know of a similar technology? I think the Rails validation framework solves the problem on the wrong level because I have found that forms often operate on more than one model.

  • Using IOperationBehavior to supply a WCF parameter

    - by Chris Kemp
    This is my first step into the world of stackoverflow, so apologies if I cock anything up. I'm trying to create a WCF Operation which has a parameter that is not exposed to the outside world, but is instead automatically passed into the function. So the world sees this: int Add(int a, int b) But it is implemented as: int Add(object context, int a, int b) Then, the context gets supplied by the system at run-time. The example I'm working with is completely artificial, but mimics something that I'm looking into in a real-world scenario. I'm able to get close, but not quite the whole way there. First off, I created a simple method and wrote an application to confirm it works. It does. It returns a + b and writes the context as a string to my debug. Yay. [OperationContract] int Add(object context, int a, int b); I then wrote the following code: public class SupplyContextAttribute : Attribute, IOperationBehavior { public void Validate(OperationDescription operationDescription) { if (!operationDescription.Messages.Any(m => m.Body.Parts.First().Name == "context")) throw new FaultException("Parameter 'context' is missing."); } public void ApplyDispatchBehavior(OperationDescription operationDescription, DispatchOperation dispatchOperation) { dispatchOperation.Invoker = new SupplyContextInvoker(dispatchOperation.Invoker); } public void ApplyClientBehavior(OperationDescription operationDescription, ClientOperation clientOperation) { } public void AddBindingParameters(OperationDescription operationDescription, BindingParameterCollection bindingParameters) { // Remove the 'context' parameter from the inbound message operationDescription.Messages[0].Body.Parts.RemoveAt(0); } } public class SupplyContextInvoker : IOperationInvoker { readonly IOperationInvoker _invoker; public SupplyContextInvoker(IOperationInvoker invoker) { _invoker = invoker; } public object[] AllocateInputs() { return _invoker.AllocateInputs().Skip(1).ToArray(); } private object[] IntroduceContext(object[] inputs) { return new[] { "MyContext" }.Concat(inputs).ToArray(); } public object Invoke(object instance, object[] inputs, out object[] outputs) { return _invoker.Invoke(instance, IntroduceContext(inputs), out outputs); } public IAsyncResult InvokeBegin(object instance, object[] inputs, AsyncCallback callback, object state) { return _invoker.InvokeBegin(instance, IntroduceContext(inputs), callback, state); } public object InvokeEnd(object instance, out object[] outputs, IAsyncResult result) { return _invoker.InvokeEnd(instance, out outputs, result); } public bool IsSynchronous { get { return _invoker.IsSynchronous; } } } And my WCF operation now looks like this: [OperationContract, SupplyContext] int Amend(object context, int a, int b); My updated references no longer show the 'context' parameter, which is exactly what I want. The trouble is that whenver I run the code, it gets past the AllocateInputs and then throws an Index was outside the bounds of the Array. error somewhere in the WCF guts. I've tried other things, and I find that I can successfully change the type of the parameter and rename it and have my code work. But the moment I remove the parameter it falls over. Can anyone give me some idea of how to get this to work (or if it can be done at all).

  • Looking for solution to persist rows sequence in a database table that allow efficient reordering at

    - by Chau Chee Yang
    I have a database table. There is a field name "Sequence" that indicate sequence when user presents the rows in report or grid visually. When the rows are retrieved and presented in a grid, there are few UI gadget that allow user to reorder the rows arbitrary. The new sequence will be persist in database table when user commit the changes. Here are some UI operations: Move to first Move to last Move up 1 row Move down 1 row multi-select rows and move up or down multi-select rows and drag to new position For operation like "Move to first" or "Move to Last", it usually involve many rows and the sequence those rows would need to be updated accordingly. This may not be efficient enough at runtime. It is a common practice to use INTEGER as sequence's data type. Other solution is using "DOUBLE" or "FLOAT" that could overcome the mass update of row sequence but we will face problem if we reach the limit of precision.

  • Roles authentication with Rails 3 and Devise.

    - by Oluf Nielsen
    Hi, first happy new year, may you make the best applications in 2011! So to my question, i have used devise ever since i got over to Rails 3, that was around the first or second beta, and now i also needs some Roles. So i searched the net, and i searched! And what i found was that CanCan should be the best solution. But i'm unsure if CanCan can manage my needs, like i want a forum moderator who can edit/destroy the topic, but the user who created the topic should also be able to edit, so how can i do that? Cheers, Oluf.

  • How Can I Reference Multiple Primary Keys For A Vector Type Primary Key

    - by AndreiC
    Hi, I have the following scenario: a table of projects and a table of persons, working on one or serveral projects. Also, I have a project id column (of type int), in the first table, which is a primary key there and I have a vector of project ids, as a column of type int, in my second table (persons), that references primary keys from the first table. What is the correct syntax for referencing multiple primary keys, from a vector foreign key. This is the way I am trying to create the table, but I am not sure what to place at the indicated line: CREATE TABLE Persons( Person_Id int, ..., ProjectsList int[], FOREIGN KEY (ProjectsList) REFERENCES Projects(Project_id) -- not sure what how to define the link here ); I hope my explanations are not over-complicated. Thank you in advance for helping!

  • Rails Habtm with a field

    - by moshimoshi
    Hello, Is that possible to have a field in a has and belongs to many table? Just like favorite: create_table :messages_users, :id => false, :force => true do |t| t.integer :message_id, :null => false t.integer :user_id, :null => false t.boolean :favorite, :null => false t.timestamps end I saw timestamps works well, thanks to ActiveRecord. But when I try to add favorite into the table and then I try: Message.first.users << User.first Then I get this error message: ActiveRecord::StatementInvalid: SQLite3::SQLException: messages_users.favorite may not be NULL: INSERT INTO "messages_users" ("created_at", "message_id", "updated_at", "user_id") VALUES ('''2010-05-27 06:07 :50.721512''', 1, '''2010-05-27 06:07:50.721512''', 1) I would like to use a habtm, I don't like has_many foo though bar association :) Is that possible? Thanks a lot.
